In the first recipe , I introduced the composite shape approach and its implementation in gfx. I explained how it works and how to handle the challenge of complex graphical representation like coordinates conversion and user interactions. In this new recipe, we will go one step further and see how to implement a custom composite shape to build a data-aware graphic component. Custom composite shape The first step in a custom composite shape... [More]

As promised in my previous article about creating a custom Dojo gauge representing a bullet graph , here is a quicjk article that shows how to leverage the dojox/mvc module to automatically bind the value of the gauge to a data model being modified over time. Thanks to the flexibiltiy of the dojox/mvc module, all you need to do for that is use the dojox/mvc/at binding syntax in your markup to link the value of the BulletGraph gauges instance to... [More]

The dojox.gfx API provides a set of basic graphic shapes that cover all the 2D shape types spectrum. While this set of shapes allows building all kind of drawings made of individual shapes, complex graphical representations requires a different structure in order to be handled as one unique graphic object. It is particularly true when building business applications
that use specific symbology. The answer to this use case is composite 2D... [More]

A while ago I wrote a series of blog posts about a data visualization component called the Bullet Graph that I had developed on top of IBM ILOG Elixir gauges framework. This component is basically trying to mix
some of the bar graph and horizontal gauge concepts to take the best of
both worlds and convey data information in a more efficient way. The
component was first described by Stephen Few in its Information Dashboard Design book. You... [More]
